ATOMIZE'R.

SPECIFICATION forming part of Letters Patent No. 553,? 65, dated. January 28, 1896.

Application filed January-23, 1895. Serial No. 535,975. (No model.) Patented in- Germany August 24:, 1893, No. 77,180; in

England January 5,1894,1111.S09,andiuAustria-Hungary April 26, 1894,1T0. 165/9,'780- T0 in whom it may concern:

Be it known that I, CARL RUPPOLI, a citizen of the German Empire, residing at Berlin, in the Kingdom of Prussia, German Empire, have invented certain new and useful Improvements in Spray-Producers, (for which I have obtained patents in Germany, No. 77,180, dated August 24, 1893; in Great Britain, No. 309, dated January 5, 1894, and in Austria, No. 165/9,780,dated April 26, 1894;) and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same. My invention relates to a spray-producer which differs from the apparatus-heretofore used in that it is not intended to be blown with the mouth, two of its sides being pressed together to cause an effective spraying of the liquid. WVith this improved apparatus I may also produce either a full jet or. discharge the liquid in drops.

In the. accompanying drawings, Figure l is a side elevation, partly in section, of one form of my improved apparatus. I Fig. 2 is a plan or edge view thereof. Fig. 3 is a transverse section, and Fig. 4 is a transverse section of a modified form of the apparatus shown in Fig. 3. Fig. 5 is a vertical section of the upper part of a modified form of the apparatus.

Similar letters of reference indicate corresponding parts in the several figures of the drawings.

The apparatus shown in Figs. 1 to 3 is chiefly designed as a pocket spray-producer, while that shown in Fig. 4c is made of alarge size.

of the vessel asunder again on the pressure of the thumb and finger being relaxed. The said vessel contains the liquid to be atomized, which is ejected through a fine tube f and an aperture 6, owing to the fact that on the two parts of the vessel being pressed together the oblique direction, therebyproducing a very v fine spray. The vessel a is provided with an interiorly-screw-threaded neck 0 adapted to receive a screw plug d with an inner cav-v ity, to the periphery of which the before mentioned tube f is soldered and which terminates in a taper depression or bore. Almost immediately in front of the aforesaid aperture 6 is the end of the tube f, which is pointed a little in order that a sufficient space may be left. between its orifice and. the said aperture for the simultaneous outlet of the compressed air. 7

In casethe spray-producer is to be carried in the pocket it is necessary to obviate the accidental outlet of the liquid. pose I provide above the said aperture 6-, as shown in Fig. 2, a disk 9 adapted to be turned about a pin or a screw 5 and providedwith a slot h for a second screw, 8. By taking hold of a nose or projection g on the disk 9 the latter may be displaced, so'tha-t either the hole 1' at the center of the disk will be just above the aforesaid aperture 6 and allow the liquid to pass out freely, as shown in Fig. 1, or that the said disk will be 011 one side and cover the aperture e, thus preventing the liquid from passing out, as shown in Fig. 2. The screw-plug 61 may be easily removed from the neck 0 secured to the vessel a in order to enable the latter to be supplied with fresh liquid. If this spray-producer is turned so that the said aperture 6 is directed sidewise, the liquid will pass into the interior cavity of the screw-plug'cl, and if the two parts of the vessel-a are then pressed together no air can pass out with the liquid, which is forced out alone in the form of a thin jet. Moreover, by holding the spray-producer lightly in the hand and swinging it with a jerk the liquid will be ejected in the form of drops from the apertpre e. The apparatus may therefore also be used for letting drops fall on handkerchiefs, garments or the like. Instead of having a round form the cap may also be made of heX- For this pur metal must be more or less strongly arched to the outside in order that in each bending it will decrease the inelosed interior space as much as possible, whereby the air above the liquid is compressed and powerfully atemizes the jet of liquid'expelled. The spring I) may also be entirely dispensed with if it need not be feared that the arched surface of the caps will be bent through to such an extent that it passes beyond the stretched or level position inward, whereby the effectiveness would at once be rendered m'l, as it is withdiflic-ulty possible to bend the caps again outward without severing the connection at a. Such plain caps have the advantage that they-can better be ornamented than the corrugated caps. They may also receive other forms than the round form represented, whereby a greater variety in ihe outer shape of these sprayproducers can be obtained. The provision of other ornaments-for instance, enamels,

painting and the likecan be more easily-effected'on plain caps than on corrugated ones.

In thearrangementshown in Fig. 5 the tube f soldered to the screw-plug d is bent to an angle and terminates within a nipple provided with an opening e, which tube also leaves in the said nipple a small intermediate space for the simultaneous outlet of the air compressed by the two parts of the vessel (1. Thesaid nipple 7c is inserted into a cap Z which forms a collecting chamber for the compressed air. air inlet-valve, which consists of a sheet q of mica with a sieve p of wire-gauze underneath. Both are covered by a small disk 9" which has an aperture at the center. In order to protect this valve from injury or keep ofi. the dust I provide it with a small cap a having lateral holes 0. This valve serves for rapidly replac-. ing the air which is used each time the two parts of the vessel a are pressed together. \Vhile in the pocket spray-producer, Figs. 1 to 3, the fresh air enters through the same aperture 6 through which the compressed air has passed out, I provide in the larger spray-producer, Fig. 5, a separate air-inlet at 0 0 with the before-described valve. For large spray- Upon this cap Z is 'mounted an producers the aforesaid opening (2 is too small for letting the air through with sufficient rapidity when the sides of the vessel rapidly expand again after they have been pressed together. Accordingly this separate air-inlet will be required if thesaid sides exceed a certain size-that is to say, the apparatus is to be made not as a pocket spray-producer, but for use on a table or for similar purposes. It is then expedient to provide the vessel a, with legs or a stand by which it can be supported upon the table.

What I claim is- 1. In a spray-producer, the combination with a compressible vessel (1, provided with a suitable neek, of a plug detachably connected to said neck and having an internal bore terminating in an outlet-opening, and a deliverytubelead'ing from within the vessel to near the mouthof the outlet-openin g, substantially as described.

2. In aspray-prod ucenthe combination with the compressible vessel ct,provided with a suitable neck, of a plug detach; connected to said neck and having an upwardly-tapering internal bore terminating at its upper end in a contracted outlet-opening, and a deliverytube of smaller diameter than the internal bore, leading from within the vessel to the mouth of the outlet-openin g, substantially as described.

3. In a spray-producer,thecombination with the compressible vessel or of a neck attached to said vessel, a pl-ug detachably'connected to the neck and provided with an upwardly-tapering bore-or 0utlet-opening,-adelivery tube leading from within the vessel to the mouth of the outlet-opening, and an apertured disk pivoted to the top of the plug, substantially as described.

i. In aspray-producer,the combination with the compressible vessel 1a of an internallythreaded neck attached tosaid vessel, anexternally-threaded plug screwed into said neck and provided with an upwardly-tapering internal bore, or'outlet-openin'g, a delivery-tube leading from within the vessel to the mouth of the outlet-opening, an apertured disk pivoted to the top of the plug and provided with a nose or projection, and means for limiting the lateral movement of the disk, substantially as described.

In witness whereof I have hereunto set my hand, at Berlin, this 21st day of December, 1894:.
